When the tail-section crashed into the water she was pulled out by Mr. Eko, and brought back to consciousness after Ana-Lucia administered CPR. Her brother [Zack] was also traveling with her. She was watched over by Libby and Cindy when danger would strike. She lived among the other Tail Section survivors until Day 12 when she was abducted by The Others. Her name and description was on a list of other survivors found in the pocket of the woman Ana-Lucia killed defending herself. (The Other 48 Days)

Emma proceeded with the rest of her group away from the cages. (Stranger in a Strange Land)
